The function of the AC-M11 is based on a cooling circuit and two powerful fans. The evaporator section contains the evaporator and a radial fan, which draws warm internal air of the tent through the cold evaporator and blows out the cooled air through the side or the top of the unit. The condenser section contains two condenser coils and a large axial fan, returning the heat taken from the internal air to the outside atmosphere. 

The AC-M11 is equipped with an electric heating coil, to provide heating for example for night time when temperatures can fall under 20°C. 

All sheet metal parts are protected against corrosion by a minimum 80μm top coat.
